When the device is to be used, theca'sing drawn, and said container'maybe removed from the reel of rope, or may be thrown out of thewindowbodily with said reel. In either instance, the rope will readilyunwind from the reel'and will hang' out ofthe window. The bailsfilof'the main body are I now disengaged from the hook 60 and the throughthe lower portion'of the frame 12 and will climb out of the window. -HisI eccentrics 44 -toincrease or diminish 1 his 2 6O andthe loop 58 isengaged with said hook,

weight causes descent of themain body of the device along the rope 22and the various friction-creating devices hereinbefore described,control the rate of' descent. If de-' sired, the occupantmay operate oneof the speed. When one person has descended, *another may pull the rope22 upwardly, thus again elevating the main body of. the device, tothefioor from which the descent was made. Then, the loop 59' is removedfrom'the hook so that the end of the rope having said loop 59 may bethrown 'outof the window. Assuming that the rope engaged the shoe 20,the roller 36 and the parts 44*41', during the preceding descent, saidrope will'now'be dis engaged from these parts and will be en-' gagedwiththe shoe 20*, the roller 36, the

, eccentric 44, and the lever end 41 at the opposite side of the device,for the second descent. Hence, it'will be seen that the device may beadvantageously used as many 'times as desired, in succession, it beingonly 11.
